Design, synthesis and biological evaluation of 2-[1-(pyridin-2-ylmethyl)-1H-pyrazole-3-carboxamido]benzoic acids as promising urate transporter 1 inhibitors with potential nephroprotective efficacy for the treatment of hyperuricemic nephropathy. Eur J Med Chem 2025; 290:117507. [PMID: 40101451 DOI: 10.1016/j.ejmech.2025.117507] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 01/05/2025] [Revised: 03/01/2025] [Accepted: 03/11/2025] [Indexed: 03/20/2025]
Abstract
Hyperuricemic nephropathy (HN) is considered an important risk factor for mortality in patients with hyperuricemia. Reducing serum uric acid (UA) levels and mitigating kidney injury are essential components in the treatment of HN. Thus, UA-lowering drugs that can also protect the kidneys are urgently needed. We identified a urate transporter 1 (URAT-1) inhibitor, T29, with cytoprotective efficacy through screening an internal library against hyperuricemia using a UA-induced HK-2 cell injury model. A bioisosteric strategy was then employed to replace the indole core of T29 with pyrazole moieties; this resulted in a series of 2-[1-(pyridin-2-ylmethyl)-1H-pyrazole-3-carboxamido]benzoic acids. Among them, compound 18 demonstrated the best cytoprotective efficacy (cell viability = 92.2 % vs. model = 31.5 %), and the IC50 value of compound 18 against URAT-1 was 3.36 μM; both of these values exceeded T29. In an HN mice model induced by a 0.75 % adenine diet and intraperitoneal injection of potassium oxonate (400 mg/kg), compound 18 significantly reduced the serum UA levels by inhibiting URAT-1 activity. Furthermore, compound 18 improved kidney function by lowering serum creatinine (CRE) and urea nitrogen (BUN) levels while attenuating tubular dilation and inflammatory cell infiltration in the kidneys. Additionally, it suppressed the release of the proinflammatory cytokines IL-1β and TNF-α and reduced kidney fibrosis by downregulating the expression of α-SMA and TGF-β. In conclusion, compound 18 ameliorated HN by inhibiting URAT-1, alleviating immune-inflammatory responses and mitigating fibrosis; the results from this study demonstrate its potential as a therapeutic agent for HN.

Abstract
BACKGROUND Plant diseases caused by phytopathogenic fungi continue to threaten global food security, driving the urgent need for discovery of antifungal agrochemicals with novel modes of action. The motif of 1,5-diaryl-3-trifluoropyrazole was found to be associated with potential antifungal effect and HNNK-5 was such an agrochemical being developed in our lab with moderate potency. This study took HNNK-5 as the parent compound for lead optimization to discovery novel fungicides. RESULT To further explore the antifungal potential of this class of compounds, a series of analogues of HNNK-5 was designed and prepared. Among them, compound 7 was identified as the most potent member with much improved activity over the lead compound. Compound 7 almost completely inhibited the growth of all the tested fungal pathogens at 50 μg/mL with an EC50 range of 6.2-11.5 μg/mL, multiple-fold less potent than the positive control azoxystrobin. Scanning electronic microscope (SEM) observation and fatty acid analysis showed that compound 7 treatment caused morphological changes and altered the amount of fatty acids of Fusarium oxysporum. Furthermore, compound 7 at higher application rates showed pronounced controlling effects against peanut root rot disease caused by Fusarium oxysporum in field study, similar to those of positive control azoxystrobin. CONCLUSION This study indicated that the characteristic structure of 1,5-diaryl-3-trifluoropyrazole could be employed as a potential skeleton for antifungal pesticides development and provided compound 7 as a promising pesticide candidate for further development. © 2025 Society of Chemical Industry.

[PMID: 40424638 DOI: 10.1002/cbdv.202500040] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 01/04/2025] [Revised: 04/30/2025] [Accepted: 05/05/2025] [Indexed: 05/29/2025]
Abstract
A novel pyrazole-1,2,3-triazole hybrids were developed and evaluated for its glucosidase inhibitory effects. The targeted 1,2,3-triazole hybrids were obtained from the copper-catalyzed reaction between azide and pyrazole alkyne in dichloromethane at room temperature. Compounds with 4-nitro and 4-chloro groups, respectively, proved the most significant, promising α-glucosidase inhibition activity with IC50 values of 3.35 and 6.58 µM, related to the cited inhibitor, acarbose (IC50 = 3.86 µM). Further, molecular docking studies of the most active compounds were carried out, and the results demonstrated considerable binding modes in the active site of the human lysosomal acid-alpha-glucosidase enzyme. In addition, the density functional theory was carried out to predict the electronic properties of active ligands. Structure-activity relationship analysis implied that the electron-leaving functions at the para position account for the variable enzyme inhibition. Therefore, developing novel therapeutic agents may assist as structural models in exploring diabetes mellitus.

Abstract
Candida albicans, an opportunistic fungal pathogen, is the most prevalent species among the twenty types of Candida responsible for candidiasis in humans. The condition is characterized by symptoms such as itching, redness, skin rashes, fever, septic shock, and infections of mucous membranes. This study explores the potential of pyrazolones and their AI-generated derivatives as effective treatments for these fungal infections. We conducted molecular docking, quantum molecular simulations, drug-likeness study, spectroscopic analysis, electrostatic potential analysis, and topological analysis to evaluate the potential of these derivatives as effective pharmaceuticals alongside molecular dynamics (MD) simulations. Our results show that several of these derivatives bind strongly to the target protein N-myristoyl transferase (NMT), showing a range of binding energies from -9.2 to -9.8 kcal/mol. Further insights revealed that D1 interacts with the NMT protein through two hydrogen-bonding residues HIS-227 and LEU-355, while D2 forms hydrogen bonds with ASP-110 and VAL-108. The ADMET profiling performed using the pkCSM platform identified D1 as a lead candidate, exhibiting optimal intestinal absorption and a maximum total clearance rate, which aligns with the criteria for drug-likeness and therapeutic viability. Additionally, our results showed that these derivatives had stronger binding affinities as compared to the parent compound. Molecular dynamics simulations of selected complexes (D1, D2, D5, and D6) over 120 ns demonstrated their structural stability and dynamic flexibility, as indicated by metrics encompassing root mean square fluctuation (RMSF), root mean square deviation (RMSD), radius of gyration (Rg), and solvent accessible surface area (SASA). The values of RMSD, remaining well within the permissible 4 Å threshold, reflect minimal structural fluctuation, that support the concept of stable complexes during the simulation. Quantum chemical calculations revealed that D1 and D4 had enhanced reactivity, which may improve their ability to interact with biological targets. This study also compared experimental and theoretical approaches to analyzing the properties of the parent compound. Our computational findings demonstrate that derivatives D1 and D2 exhibit strong binding to NMT, a validated antifungal target, with interactions critical for disrupting fungal cell viability. ADMET profiling further identifies D1 as a promising lead with favorable pharmacokinetics, suggesting its potential to inhibit Candida albicans growth in vivo. These results position our derivatives as biologically relevant candidates for experimental validation, advancing the development of novel antifungal therapies.

Abstract
In this study, we reported the utilization of vinylsulfonium salt as a highly efficient dipolarophile, leveraging the facile leaving ability of its sulfide moiety, to engage in a [3 + 2] cycloaddition with N-amino(iso)quinolinium salts. This approach facilitates the construction of various C1/C2-unsubstituted pyrazolo(iso)quinoline skeletons. The transformation is conducted under catalyst- and external oxidant-free conditions. Furthermore, the extended gram-scale reaction demonstrates the practical applicability of the developed protocol.

Abstract
The development of anti-inflammatory compounds is crucial because of the complexity of the wound-healing process associated with bacterial infections. Anti-inflammatory compounds have been rapidly developed for use in biomedical fields. In this study, three new skin fibroblast cell promotors (pyrazolone derivatives) with pyrazolone cores were designed and synthesized to evaluate their inhibitory effects on the cyclooxygenase-2 enzyme. The pyrazolone derivatives were characterized using FTIR, 1H and 13C NMR, and DSC. These pyrazolone derivatives exhibited excellent biocompatibility, resulting in significant proliferation of NIH/3 T3 fibroblast cells, as confirmed through fluorescence microscopy in the live-dead cell assay. Moral anti-inflammatory property was verified by the strong interactions between inflammation-responsible enzyme 6-COX and ligands. In vitro anticancer activity assessments revealed that the pyrazolone derivatives did not reduce the viability of breast cancer MDA-MB231 cells as opposed to the control group. Additionally, the pyrazolone derivatives displayed great antibacterial activity against Staphylococcus aureus and Escherichia coli, with a 100 ± 0.1 % inhibitory efficiency for 24 h. Moreover, the pyrazolone derivatives showed good antifungal activity against Aspergillus flavus, effectively inhibiting the secretion of aflatoxins (98 ± 0.1 %). Our results demonstrated that these newly synthesized pyrazolone derivatives are promising candidates for application in anti-inflammatory or wound-dressing treatments.

Abstract
Herein, we describe a protocol for Brønsted acid-catalyzed regioselective coupling of azoles such as pyrazoles, 1,2,3-triazole, 1,3,4-triazole, benzotriazole, indazole and tetrazole, to cyclobutenes. These azoles could be directly coupled with various arylcyclobutenes with high site-selectivity, offering a distinct entry to more functionalized cyclobutanes. The usage of inexpensive TsOH ⋅ H2O catalyst, broad substrate scope, and open-air conditions make this protocol practically viable. This study not only contributes a feasible tool for selective functionalization of cyclobutenes, but also provides a strategy to introduce cyclobutane moieties into complex molecules.

Abstract
The association and causal role of infectious agents in chronic inflammatory diseases have major implications for public health, treatment, and prevention. Pharmacological treatment of combined infectious and inflammatory diseases requires the administration of multiple drugs, including antibiotics and anti-inflammatory drugs. However, this can cause adverse effects, and therefore, dual-action drugs need to be developed. Anti-inflammatory drugs that have already shown antimicrobial properties appear to be promising candidates. NSAIDs, namely aceclofenac, diclofenac, and ibuprofen, were tested in clinical trials with patients diagnosed with uncomplicated urinary tract infections (UTIs) and cellulitis. The administration of ibuprofen, a drug tested in the highest number of studies, resulted in symptom resolution in patients with UTIs. Additionally, ibuprofen caused a high survival rate in mice infected with Pseudomonas aeruginosa and demonstrated potent in vitro antibacterial effects against Bacillus cereus, Escherichia coli, and Staphylococcus aureus, including methicillin-resistant S. aureus (MRSA) (MIC 0.625-2.5 mg/L). For most anti-inflammatory drugs, only data showing their in vitro and in vivo antimicrobial effects are available. Among these, auranofin caused a high survival rate in mice infected with Enterococcus faecium, S. aureus, and Clostridioides difficile. It also produced a strong in vitro growth-inhibitory effect against Streptococcus agalactiae, S. pneumoniae, S. aureus, S. epidermidis, Bacillus subtilis, C. difficile, E. faecalis, E. faecium, and Mycobacterium tuberculosis (MIC 0.0015-5 mg/L). Similarly, aspirin caused a high survival rate in M. tuberculosis-infected mice and strong to moderate in vitro activity against E. coli, B. cereus, P. aeruginosa, Enterobacter aerogenes, Klebsiella pneumoniae and Salmonella choleraesuis (MIC 1.2-5 mg/L). Moreover, topical application of celecoxib resulted in a high reduction in MRSA burden in mice. However, it only caused moderate in vitro effects against S. epidermidis, S. aureus and Bacillus subitilis (MIC 16-64 mg/L). These data suggest that certain non-steroidal anti-inflammatory drugs (NSAIDs) are promising drug candidates for the development of dual-action drugs for the potential treatment of combined infectious and inflammatory diseases such as tuberculosis, musculoskeletal infections and UTIs. Nevertheless, future clinical trials must be conducted to ascertain the antibacterial effect of these NSAIDs before their practical use.

Abstract
Biofilm is a "growing" problem and needs effective remedial agents. Here we report novel methyl 4-((4-(4-chlorophenyl)-2,5-dioxoimidazolidin-1-yl) methyl) benzoate derivatives (5a-l) as antibiofilm and antimicrobial agents evaluated with both in silico and in vitro techniques. When it comes to Gram-positive bacterial strains like Staphylococcus aureus (MTCC 737), MRSA and Streptococcus pneumoniae (MTCC 1936), and Gram-negative bacterial strains like Pseudomonas aeruginosa (MTCC 424) and Escherichia coli (MTCC 443), the minimum inhibitory concentration (MIC), minimum biofilm inhibition concentration (MBIC), and anti-biofilm activity were measured. Out of all the compounds (5a-l), 5b and 5d showed no toxicity to mammalian cells and were equally active against various Gram-positive and Gram-negative bacteria at low concentrations (MIC: 0.1-9.5 µg/mL). Compounds 5b and 5d were also validated for the DNA gyrase inhibition potential as an antimicrobial mechanism of action in vitro. These compounds showed high level DNA gyrase inhibition potentials (IC50 0.025 µM, ≥ 98 relative % activity and 0.24 µM, ≥ 94 relative % activity respectively. In the end, we have identified 5b and 5d as most effective among 5a-l and are considered for further preclinical studies.

Chem Biodivers 2025; 22:e202402457. [PMID: 39523465 DOI: 10.1002/cbdv.202402457] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 09/29/2024] [Revised: 10/27/2024] [Accepted: 11/09/2024] [Indexed: 11/16/2024]
Abstract
This study explores new anti-inflammatory agents by synthesizing pyrazoline-pyridine hybrids with N-butylsulfonated covalent organic framework (COF-SO3H) as a recyclable catalyst, achieving excellent yields in just one minute. The protocol was successfully scaled up to a multi-gram scale, highlighting its robustness and efficiency, and it operates without the need for column chromatography. Among the synthesized hybrids, compound 5d, a pyrazoline-pyridine hybrid bearing an indole moiety, emerged as a potent anti-inflammatory and antioxidant agent. It effectively inhibited PDE4B activation with an IC50 value of 99.38 nM, without adversely affecting HEK cells. Compound 5d demonstrated its dual activity by significantly reducing ROS production and restoring mitochondrial health in LPS-stimulated A549 and HEK cells, while also downregulating IL-1β and NF-ĸB/p65 expression in LPS-stimulated A549 cells. In silico studies confirmed compound 5d's strong binding to PDE4B, with stable RMSD and RMSF values, indicating its potential as a stable and effective PDE4B inhibitor. The compound exhibited favorable physicochemical properties, met drug-likeness criteria, and showed low toxicity as predicted in silico. These findings suggest that compound 5d has significant potential as a therapeutic agent for inflammatory diseases due to its dual anti-inflammatory and antioxidant activities.

Abstract
The present review serves to highlight the antitumor worth of pyrazole derivatives. Several active pyrazole-based anticancer compounds proposed by a huge number of scientists worldwide are reported. Regarding the development of novel pyrazole-based anticancer agents at a faster tone, there is a need to correlate the latest information with previously available information to understand the situation of this moiety in anticancer drug discovery studies. Herein, different anticancer pyrazoles are classified according to their mode of action at different anticancer targets. The results provided evidence that pyrazole derivatives have potential applications for the treatment of a variety of tumor types. From the study's findings, the structure-activity relationship (SAR) results demonstrated that all the compounds containing substituted pyrazole represent an important scaffold for anticancer activities. Publications in this area are increasing, and therefore, new therapeutic applications involving members of pyrazole derivatives could be discovered in the near future, as many prospects have not been sufficiently studied so far for other targets. In other words, this review provides an overview of the state of knowledge about the structural characteristics of the most recent anticancer pyrazole derivatives and their SAR with various targets. This will allow medicinal chemists to identify promising structures to guide the design and synthesis of more effective and safer anticancer candidates.

Abstract
We present a photocatalytic method for alkylamination of alkenes, enabling efficient C-C and C-N bond formation to construct aza-heterocycles valuable in drug discovery. Using a radical-polar crossover pathway, electron-deficient alkenes are reduced to electrophilic radicals, which react with electron-rich alkenes to form nucleophilic radicals. Oxidation of these intermediates yields carbocations, which are trapped by aza-heteroarenes to afford alkylaminated products. This strategy enhances molecular complexity while suppressing side reactions.

Abstract
The current research focused on the synthesis of two series of pyrazole derivatives and evaluation of their insecticidal effectiveness. In the first series, seven pyrazole Schiff bases 3a-g were successfully synthesized with yields (79-95%) by condensing phenylfuran-2-carbaldehyde with substituted pyrazole rings. In the second series, eleven amino acid-pyrazole conjugates 6a-k were synthesized utilizing acetic acid, sulfuric acid, morpholine, and EDC. HCl achieving yields of 59% to 94%. The synthesized compounds were assessed for their chemotherapeutic efficacy against locusts and termites by calculating LC50 values, thereby determining their potential as anti-termite and anti-locust agents. Among the eighteen synthesized pyrazole compounds, the Schiff base pyrazole molecules 3f (LC50 = 0.001 μg/mL) and 3d (LC50 = 0.006 μg/mL) demonstrated excellent anti-termite activity compared to the reference drug fipronil (LC50 = 0.038 μg/mL). Pyrazole derivative 6 h with LC50 = 47.68 μg/mL exhibited superior anti-locust activity than the reference drug fipronil (LC50 = 63.09 μg/mL). Additionally, compound 3b, containing NO2 functionality at the meta position, exhibited notable and significant anti-locust activity with an LC50 values of 100.00 μg/mL. However, the highest mortality was caused by the glycine conjugate of fipronil 6 h of the 2nd series with an LC50 value of 47.68 μg/mL, which also proved to be a potent anti-locust agent. This study explores the efficacy of biologically active pyrazole structures as potential insecticidal agents through a combination of virtual molecular docking analysis and biological experimental investigations. The results demonstrate a strong correlation between the computational predictions and experimental outcomes, suggesting that the pyrazole derivatives exhibit significant insecticidal properties. The findings highlight the potential of these compounds in the development of innovative insecticides, paving the way for future research in pest control strategies.

Abstract
This paper describes an iridium-catalyzed allylation of ring-fused pyrazolones that proceeds with excellent regio-, diastereo- and enantio-selectivities. The approach exploits unactivated, racemic allylic alcohols as a source of allyl building blocks. Asymmetric syntheses of a series of biologically relevant, chiral pyrazolones highlight the utility of the methodology. The use of Cu(OTf)2 as a co-catalyst greatly enhances the regioselectivity of the reaction and permits selective syntheses of branched allylation products.

Abstract
New haloaminopyrazole derivatives differing in the number of pyrazole nuclei 4a-f and 5a-e, respectively, were synthesized and characterized by 1H-NMR, 13C-NMR, IR, UV-Vis, and elemental analysis. The single-crystal X-ray diffraction method was used to describe compounds 4a and 5d. When tested on normal NCTC fibroblasts in vitro, the newly synthesized derivatives were shown to be non-cytotoxic at a dosage of 25 μg/mL. Two compounds 4a and 5d showed a high degree of biocompatibility. From the two series of compounds tested on HEp-2 human cervical carcinoma cells, compound 5d showed a more pronounced antiproliferative effect. Gram-positive strains of Staphylococcus aureus ATCC25923, Enterococcus faecalis ATCC29212, Gram-negative strains of Pseudomonas aeruginosa ATCC27853, and strains of Escherichia coli ATCC25922 were used to test the newly synthesized compounds antibacterial and antibiofilm properties. Among the studied pyrazole compounds, 2 compounds 4a and 5a with fluorine content on the phenyl ring and 4 compounds 4b, 4e, 4f, and 5b with chlorine content on the phenyl ring were noted, which proved to be the most active compared with the two reference drugs, metronidazole and nitrofurantoin. The six compounds showed a broad spectrum of action against all four tested bacterial strains, the most active being compound 4b, with a chlorine atom in the "4" position of the phenyl nucleus and a MIC of 460 μg/mL. Compounds 4a and 5a showed the best antibiofilm activity against the bacterial strain Staphylococcus aureus ATCC25923, with an MBIC of 230 μg/mL.

Abstract
Aza-heterocyclic scaffolds are privileged cores in the composition of their potential therapeutic profiles and versatile synthetic intermediates. Pyrazole is one of the frequently studied compounds of "azole" family and consists of nitrogen in a 1,2 linking sequence. These motifs possess a wide-spectrum of applications in the field of pharmaceuticals, agrochemicals, polymer chemistry, cosmetics, food industries and more. In addition, functionalized pyrazole derivatives are frequently used as ligands in coordination chemistry and metal-catalysed reactions. As exemplified by numerous recent reports, pyrazoles are highly promising pharmacophores with excellent therapeutic applications. Owing to their aromaticity, the ring structures have many reactive positions, where electrophilic, nucleophilic, alkylation and oxidative reactions might occur. The structural adroitness and diversity of pyrazole cores further emanated numerous fused bicyclic skeletons with various biological applications. In this review, we highlight the recent synthetic methods developed for the preparation of functionalized pyrazole derivatives (From 2017 to present). In addition, we have also covered the notable biological activities (anti-cancer, anti-inflammatory, anti-bacterial and anti-viral) of this ubiquitous core. Herein, we emphasised the synthesis of pyrazoles from variety of precursors such as, alkynes, α,β-unsaturated carbonyl compounds, diazo reagents, nitrile imines, diazonium salts, 1,3-dicarbonyl compounds and etc. Moreover, the recent synthetic methodologies focusing on the preparation of pyrazolines and pyrazolones and variously fused-pyrazoles are also included. Authors expect this review could significantly help the researchers in finding elegant novel tools to synthesize pyrazole skeletons and expand their biological evaluation.

Abstract
This study aimed to explore the antioxidant potential of the ethyl acetate extract of Streptomyces coeruleofuscus SCJ strain, along with its inhibitory effects on the triple-negative human breast carcinoma cell line (MDA-MB-468). The ethyl acetate extract's total phenolic and flavonoid contents were quantified, and its antioxidant activity was investigated using DPPH (1,1-Diphenyl-2-picrylhydrazyl), ABTS (2,2'-azino-bis (3-ethylbenzothiazoline-6-sulphonic acid), and FRAP (Ferric Reducing Antioxidant Power) assays. Furthermore, the cytotoxic effect of the organic extract from Streptomyces coeruleofuscus SCJ on MDA-MB-468 cancer cells was assessed via the crystal violet assay. In tandem, a thorough computational investigation was conducted to explore the pharmacokinetic properties of the identified components of the extract, utilizing the SwissADME and pKCSM web servers. Additionally, the molecular interactions between these components and Estrogen Receptor Beta, identified as a potential target, were probed through molecular docking studies. The results revealed that ethyl acetate extract of SCJ strain exhibited remarkable antioxidant activity, with 39.899 ± 1.56% and 35.798 ± 0.082% scavenging activities against DPPH and ABTS, respectively, at 1 mg/mL. The extract also displayed significant ferric reducing power, with a concentration of 1.087 ± 0.026 mg ascorbic acid equivalents per mg of dry extract. Furthermore, a strong positive correlation (p < 0.0001) between the antioxidant activity, the polyphenol and the flavonoid contents. Regarding anticancer activity, the SCJ strain extract demonstrated significant anticancer activity against TNBC MDA-MB-468 cancer cells, with an inhibition percentage of 62.76 ± 0.62%, 62.67 ± 0.93%, and 58.07 ± 4.82% at 25, 50, and 100 µg/mL of the extract, respectively. The HPLC-UV/vis analysis revealed nine phenolic compounds: gallic acid, sinapic acid, p-coumaric acid, cinnamic acid, trans-fereulic acid, syringic acid, chloroqenic acid, ellagic acid, epicatechin. Streptomyces coeruleofuscus SCJ showed promise for drug discovery, exhibiting antioxidant and anticancer effects.

Abstract
Sulfur-containing compounds have diverse biological functions and are crucial in crop protection chemistry. In this study, a series of novel 1-methyl-1H-pyrazol-5-amine derivatives incorporating disulfide moieties were synthesized and evaluated for their antimicrobial properties. In vitro bioassays demonstrated that compound 7f displayed potent antifungal activity against Valsa mali, with an EC50 value of 0.64 mg/L, outperforming allicin (EC50 = 26.0 mg/L) but lower than tebuconazole (EC50 = 0.33 mg/L). In vivo experiments confirmed that compound 7f could effectively inhibit V. mali infection on apples at a concentration of 100 mg/L, similar to the positive control tebuconazole. Mechanistic studies revealed that compound 7f could induce hyphal shrinkage and collapse, trigger intracellular reactive oxygen species accumulation, modulate antioxidant enzyme activities, initiate lipid peroxidation, and ultimately cause irreversible oxidative damage to the cells of V. mali. Additionally, compound 7b exhibited notable antibacterial activity, particularly against Pseudomonas syringae pv. actinidiae, with a MIC90 value of 1.56 mg/L, surpassing the positive controls allicin, bismerthiazol, and streptomycin sulfate. These findings suggest that 1-methyl-1H-pyrazol-5-amine derivatives containing disulfide moieties hold promise as potent candidates for the development of novel antimicrobial agents.

Abstract
In this paper, we developed a highly enantioselective alkylation of 4-substituted pyrazolones catalyzed by phase-transfer catalysis. Cheap halohydrocarbons were employed as electrophilic alkylationg agents, and propargyl, allyl, and benzyl products with all-carbon quaternary stereocenters were afforded with excellent enantioselectivities and good yields. We found that the unique structures of the catalyst (hydrogen bond donors of the C-9 hydroxyl group and amide group, the triphenyl at the NH-position) were important for good enantioselectivity. Furthermore, chiral propargyl products could be easily connected to azide molecules by click cycloaddition, which offers unique opportunities to obtain structurally diverse chiral pyrazolones.

Abstract
A straightforward umpolung approach to regioselectively N-protected polysubstituted pyrazoles starting from aromatic α-halohydrazones and terminal alkynes has been developed. In this process, azoalkenes generated in situ from α-halohydrazones are involved in the Cu(I)-catalyzed Michael addition with alkynes to give α-alkynyl-substituted hydrazones that cyclize to give the target pyrazoles in 37-85% yield. The method employs readily available starting materials and features good functional group compatibility (nitro, sulfonyl, cyano, trimethylsilyl, and primary bromoalkyl groups, esters, and alcohols are tolerated) and scalability.

Abstract
Global warming has profound effects on the living conditions and metabolism of organisms, including fish. The metabolic rate of fish increases as the temperature increases within its thermal tolerance range. Temperature changes can trigger a range of physiological reactions, including the activation of the stress axis and the production of HSPs. Under stress conditions, HSPs play a crucial role in antioxidant systems, immune responses, and enzyme activation. This study examined the effects of heat shock products (HSPs) on fish under temperature stress. Various HSP inducers (HSPis), including Pro-Tex®, amygdalin, and novel synthetic compounds derived from pirano piranazole (SZ, MZ, HN-P1, and HN-P2), were evaluated in isolated cells of sterlet sturgeon (Acipenser ruthenus) treated with temperature changes (18, 22, and 26 °C). Cells from the liver, kidney, and gills were cultured in vitro in the presence and absence of temperature stress and treated with HSPi compounds. To assess HSP27, HSP70, and HSP90 expression patterns, Western blotting was used. The HSPis and HSPi + temperature stress treatments affected the antioxidant capacity and immune parameters, among other enzyme activities. The results showed that HSPi compounds increase cell survival in vitro, positively modulate HSP expression and antioxidant levels, and decrease immune parameters. HSPi can increase A. ruthenus tolerance to temperature stress. In addition, the results indicate that these compounds can reverse adverse temperature effects. Further research is needed to determine how these ecological factors affect fish species' health in vivo and in combination with other stressors.

Abstract
Heat shock proteins (HSPs) play a crucial role in antioxidant systems, immune responses, and enzyme activation during stress conditions. Salinity changes can cause stress and energy expenditure in fish, resulting in mortality, especially in fingerlings. The purpose of this study was to examine the relationship between salinity and HSPs in stressed fish by assessing the effects of various HSP inducers (HSPis), including Pro-Tex® (800 mM), amygdalin (80 mM), and a novel synthetic compound derived from pirano piranazole (80 µM), on isolated cells from Sterlet Sturgeon (Acipenser ruthenus) exposed to 13 ‰ salinity (S13). After liver, kidney, and gill cells were cultured, the HSPi compounds were treated in vitro in the presence and absence of salinity. The expression patterns of HSP27, HSP70, and HSP90 were assessed by Western blotting. Biochemical enzymes (aspartate aminotransferase, alanine aminotransferase, alkaline phosphatase, and lactate dehydrogenase), cortisol levels, and immune parameters (component 3, immunoglobulin M, and lysozyme) were measured before and after treatment with HSPis and HSPi + S13. According to these findings, HSPis positively modulate HSP expression, immune responses, and antioxidant levels. Furthermore, they increased in vitro cell survival by maintaining cortisol levels and biochemical enzyme activities in A. ruthenus under saline conditions (P < 0.0001). In conclusion, HSPis can increase A. ruthenus resistance to salinity stress. However, the results also indicated that these compounds can reverse the adverse effects of salinity. The effectiveness of this approach depends on further research into the effects of these ecological factors on the health status of the species, especially in vivo and in combination with other stresses.

Abstract
Nucleophiles from deprotonation of diazomethyl compounds having diverse electron withdrawing groups react with 4-carboxylato-1,2,3-triazines at the 6-position to extrude dinitrogen and produce diazovinylketoesters compounds with five or six linear contiguous sp2-hybridized carbons, whereas these same nucleophiles react with 4-carboxylato-1,2,3-triazine 1-oxides, also at the 6-position, to form pyrazolines with the expulsion of nitrous oxide and cyanocarboxylate. This disparity is due to the significant difference in reactivity of the nucleophilic addition products.

Abstract
A highly efficient and chemoselective approach for the divergent assembling of unsymmetrical hydrazines through an unprecedented intermolecular desulfurdioxidative N-N coupling is developed. This metal free protocol employs readily accessible N-arylhydroxylamines and N-sulfinylanilines to provide highly valuable hydrazine products with good reaction yields and excellent functional group tolerance under simple conditions. Computational studies suggest that the in situ generated O-sulfenylated arylhydroxylamine intermediate undergoes a retro-[2π+2σ] cycloaddition via a stepwise diradical mechanism to form the N-N bond and release SO2.

Abstract
In a screen of over 200 novel pyrazole compounds, ethyl 1-(2-hydroxypentyl)-5-(3-(3-(trifluoromethyl) phenyl)ureido)-1H-pyrazole-4-carboxylate (named GeGe-3) has emerged as a potential anticancer compound. GeGe-3 displays potent anti-angiogenic properties through the presumptive targeting of the protein kinase DMPK1 and the Ca2+-binding protein calreticulin. We further explored the anticancer potential of GeGe-3 on a range of established cancer cell lines, including PC3 (prostate adenocarcinoma), SKMEL-28 (cutaneous melanoma), SKOV-3 (ovarian adenocarcinoma), Hep-G2 (hepatocellular carcinoma), MDA-MB231, SKBR3, MCF7 (breast adenocarcinoma), A549 (lung carcinoma), and HeLa (cervix epithelioid carcinoma). At concentrations in the range of 10 μM, GeGe-3 significantly restricted cell proliferation and metabolism. GeGe-3 also reduced PC3 cell migration in a standard wound closure and trans-well assay. Together, these results confirm the anticancer potential of GeGe-3 and underline the need for more detailed pre-clinical investigations into its molecular targets and mechanisms of action.

Investigations of Antioxidant and Anti-Cancer Activities of 5-Aminopyrazole Derivatives. Molecules 2024; 29:2298. [PMID: 38792163 PMCID: PMC11124527 DOI: 10.3390/molecules29102298] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Grants] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 04/04/2024] [Revised: 05/09/2024] [Accepted: 05/11/2024] [Indexed: 05/26/2024] Open
Abstract
To further extend the structure-activity relationships (SARs) of 5-aminopyrazoles (5APs) and identify novel compounds able to interfere with inflammation, oxidative stress, and tumorigenesis, 5APs 1-4 have been designed and prepared. Some chemical modifications have been inserted on cathecol function or in aminopyrazole central core; in detail: (i) smaller, bigger, and more lipophilic substituents were introduced in meta and para positions of catechol portion (5APs 1); (ii) a methyl group was inserted on C3 of the pyrazole scaffold (5APs 2); (iii) a more flexible alkyl chain was inserted on N1 position (5APs 3); (iv) the acylhydrazonic linker was moved from position 4 to position 3 of the pyrazole scaffold (5APs 4). All new derivatives 1-4 have been tested for radical scavenging (DPPH assay), anti-aggregating/antioxidant (in human platelets) and cell growth inhibitory activity (MTT assay) properties. In addition, in silico pharmacokinetics, drug-likeness properties, and toxicity have been calculated. 5APs 1 emerged to be promising anti-proliferative agents, able to suppress the growth of specific cancer cell lines. Furthermore, derivatives 3 remarkably inhibited ROS production in platelets and 5APs 4 showed interesting in vitro radical scavenging properties. Overall, the collected results further confirm the pharmaceutical potentials of this class of compounds and support future studies for the development of novel anti-proliferative and antioxidant agents.

Abstract
Heterocyclic hybrid frameworks represent a burgeoning domain within the realms of drug discovery and medicinal chemistry, attracting considerable attention in recent years. Thiazole pharmacophore fragments, inherent in natural products such as peptide alkaloids, metabolites, and cyclopeptides, have demonstrated a broad spectrum of pharmacological potentials. Given their profound biological significance, a plethora of thiazole-based hybrids have been synthesized through the conjugation of thiazole moieties with bioactive pyrazole and pyrazoline fragments. This review systematically presents a compendium of robust methodologies for the synthesis of thiazole-linked hybrids, employing the (3 + 2) heterocyclization reaction, specifically the Hantzsch-thiazole synthesis, utilizing phenacyl bromide as the substrate. The strategic approach of molecular hybridization has markedly enhanced drug efficacy, mitigated resistance to multiple drugs, and minimized toxicity concerns. The resultant thiazole-linked hybrids exhibit a myriad of medicinal properties viz. anticancer, antibacterial, anticonvulsant, antifungal, antiviral, and antioxidant activities. This compilation of methodologies and insights serves as a valuable resource for medicinal chemists and researchers engaged in the design of novel thiazole-linked hybrids endowed with therapeutic attribute.

Abstract
The present study involves the design, synthesis, and biological evaluation of a series of thirty-three, pyrazole-based and N,N-diethylcarbamate functionalized, novel aurone analogs, against AGS cancer cell line. These novel aurone analogs are obtained from the reaction of pyrazole-based 6-hydroxyaurones with diethyl carbamoyl chloride using mild basic reagent. The cytotoxic activities of these compounds were evaluated against a human gastric adenocarcinoma cell line (AGS) and disclosed some potential outcomes as several analogs were found to have cytotoxicity better than the reference drugs Oxaliplatin and Leucovorin. The structure-activity relationship (SAR) study further unveiled the critical role of replacing the hydroxyl group in ring A with a carbamoyl group for cytotoxic activity. Among these aurone analogs, 8e and 8f, with IC50 values of 6.5 ± 0.024 μM and 6.6 ± 0.035 μM, respectively, are identified as the most active compounds. Molecular docking studies were conducted against HER2, a human epidermal growth factor involved in gastric and ovarian cancer, to investigate the binding interactions between the compounds and the protein HER2, where7e and 8e exhibited maximum interactions.

Abstract
In this study, choline chloride/urea was used as a green deep eutectic solvent in the three-component reaction of hydrazine/phenylhydrazine, malononitrile, and aromatic aldehydes for synthesizing pyrazole derivatives, and in the four-component reaction of methyl/ethyl acetoacetate, hydrazine/phenylhydrazine, malononitrile, and aromatic aldehydes for synthesizing pyrano[2,3-c]pyrazole derivatives. Elemental analysis, 1H, and 13C NMR spectroscopy were used to confirm the structure of the synthesized pyrazole and pyrano[2,3-c] pyrazole derivatives. The antimicrobial effects of the synthesized pyrazole and pyrano[2,3-c] pyrazole derivatives were investigated. In antimicrobial tests, instructions from clinical and laboratory standards institutes were used. Antimicrobial study was done on pathogenic gram-positive and gram-negative species, and specialized aquatic strains and fungal species. Using choline chloride/urea, novel pyrazole derivatives and pyrano[2,3-c]pyrazole derivatives were synthesized, and other derivatives were synthesized with higher efficiency in less time than some previously reported methods. MIC (minimum inhibitory concentration) and MBC (minimum bactericidal concentration) obtained for derivatives were higher than some antibiotic drugs. Synthesis and reports of new derivatives of pyrazole and pyrano[2,3-c]pyrazole, and investigation and reports of their antimicrobial properties on gram-positive, gram-negative, and specialized aquatic and fungal species are among the novel and important findings of this study.

Antimicrobial potential of Streptomyces coeruleofuscus SCJ isolated from microbiologically unexplored garden soil in Northwest Morocco. Sci Rep 2024; 14:3359. [PMID: 38336871 PMCID: PMC10858231 DOI: 10.1038/s41598-024-53801-x] [Citation(s) in RCA: 5] [Impact Index Per Article: 5.0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 09/01/2023] [Accepted: 02/05/2024] [Indexed: 02/12/2024] Open
Abstract
Research on microorganisms in various biotopes is required to identify new, natural potent molecules. These molecules are essential to control the development of multi-drug resistance (MDR). In the present study, a Streptomyces sp., namely SCJ, was isolated from a soil sample collected from a Moroccan garden. SCJ isolate was identified on the basis of a polyphasic approach, which included cultural, micro-morphological, biochemical, and physiological characteristics. The sequence of the 16S rRNA gene of the SCJ strain showed 99.78% similarity to strains of Streptomyces coeruleofuscus YR-T (KY753282.1). The preliminary screening indicated that the SCJ isolate exhibited activity against Candida albicans ATCC 60,193, Escherichia coli ATCC 25,922, Staphylococcus aureus CECT 976, Staphylococcus aureus ATCC 25,923, Bacillus cereus ATCC 14,579, Pseudomonas aeruginosa ATCC 27,853, as well as various other clinical MDR bacteria and five phytopathogenic fungi. The ethyl acetate extract of the isolated strain demonstrated highly significant (p < 0.05) antimicrobial activity against multi-resistant bacteria and phytopathogenic fungi. The absorption spectral analysis of the ethyl acetate extract of the SCJ isolate obtained showed no absorption peaks characteristic of polyene molecules. Moreover, no hemolytic activity against erythrocytes was observed in this extract. GC-MS analysis of the ethyl acetate extract of the SCJ isolate revealed the presence of 9 volatile compounds including 3,5-Dimethylpyrazole, and pyrrolizidine derivatives (Pyrrolo[1,2-a]pyrazine 1,4-dione, hexahydro-3-(2-methylpropyl)), which could potentially explain the antimicrobial activity demonstrated in this study.

Abstract
The Caspian Sea has faced many environmental challenges, such as oil pollution. Heat shock proteins (HSPs) play a critical role in stress conditions and physiological changes caused by disease or injury. By evaluating the effects of various HSP inducers (HSPi), including Pro-Tex® (NOP: 800 mM), amygdalin (AMG: 80 mM), and a novel synthetic compound derived from pirano piranazole (SZ: 80 µm) on isolated cells from Sterlet Sturgeon (Acipenser ruthenus) treated with 75% IC50 PAH-benzo[a]pyrene (BaP; B75). This study examines whether there is a correlation between exposure to the BaP pollutant and HSPs in fish. In vitro, after culturing cells from the liver, kidney, and gills, they were treated with HSPi compounds in the presence and absence of BaP. Western blotting was used to assess HSP27, HSP70, and HSP90 expression patterns. A variety of enzyme activities were measured before (without treatment) and after treatment with HSPis and HSPi + B75, including cytochrome P450 (CYP450) activity, specific enzyme activity for acetylcholinesterase (AChE), antioxidant capacity, liver indicator enzymes, cortisol levels, and immunity parameters. When compared to the control group, cells treated with B75 showed the lowest AChE enzyme activity (p < 0.0001). CYP450 activity was highest in group B75, while HSPi caused the opposite effect (p < 0.0001). HSPi + B75 increased HSP levels and antioxidant parameters while decreasing cortisol and liver indicator enzymes (p < 0.0001). HSPi may be a powerful and reliable method for enhancing the resistance of A. ruthenus to BaP stresses before exposure. Treating cells with HSP-inducing compounds, such as NOP, AMG, and SZ, can assist them in managing stress and increase HSP (27, 70, and 90) protein expression. Furthermore, the study findings suggest that HSPis can also mitigate the adverse effects of stress, ultimately increasing cell survival and resistance.

Abstract
The thiophene bearing pyrazole derivatives (7a-j) were synthesized and examined for their in vitro cyclooxygenase, 5-lipoxygenase, and tumour inducing factor-α inhibitory activities followed by the in vivo analgesic, anti-inflammatory, and ulcerogenic evaluations. The synthesized series (7a-j) were characterized using 1H NMR, 13C NMR, FT-IR, and mass spectral analysis. Initially, the compounds (7a-j) were evaluated for their in vitro cyclooxygenase, 5-lipoxygenase, and tumour inducing factor-α inhibitory activities and the compound (7f) with two phenyl substituents in the pyrazole ring and chloro substituent in the thiophene ring and the compound (7g) with two phenyl substituents in the pyrazole ring and bromo substituent in the thiophene ring were observed as potent compounds among the series. The compounds (7f and 7g) with effective in vitro potentials were further analyzed for analgesic, anti-inflammatory, and ulcerogenic evaluations. Also, to ascertain the binding affinities of compounds (7a-j), docking assessments were carried out and the ligand (7f) with the highest binding affinity was docked to know the interactions of the ligand with amino acids of target proteins.

Abstract
Selection of biodegradable chitosan as a raw material is a smart technique due to its easy modifiability and high renewability. Herein, taking advantage of these functional characteristics, an ionic biopolymer support is produced from copolymerization of allylated chitosan (with 48 % degree of substitution) and polymerizable ionic liquid ([MEVIm]Br). Next, palladium nanoparticles are successfully stabilized in this designed support through a facile manner based on interconnected porous network, ionic nature and rich functional groups. Then, the Pd@CS-PIL structure was utilized as a heterogeneous catalyst for regioselective synthesis of pyrazole-fused heterocycles. The as-synthesized Pd@CS-PIL was characterized by various techniques such as XRD, EDX, FESEM, elemental mapping, TEM, BET, ICP, TGA, and FT-IR to better determine the structure, morphology, purity and physical properties. The obtained results revealed that the proposed nanostructure provides favorable porosity with significant specific surface area (139.2 m2.g-1), Pd nanoparticles with high dispersion (mean diameter ∼ 22.8 nm) and crosslinked nature with good thermal stability (50 % weight loss about 600 °C). Therefore, Pd@CS-PIL nanostructure showed the key features of a super-active catalyst, and pharmaceutical pyrazole-fused scaffolds were produced in favorable yields (86-96 %) under ultrasound conditions.

Abstract
Nitrogen-centered radicals (NCRs) have been widely recognized as versatile synthetic intermediates for the construction of nitrogen containing molecules of high value. As such, there has been a long-standing interest in the field of organic synthesis to develop novel nitrogen-based radicals and explore their inherent reactivity. In this study, we present the generation of aromatic N-heterocyclic radicals and their application in a novel and diverse functionalization of unactivated alkenes. Bench-stable aromatic N-heterocyclic pyridinium salts were employed as crucial NCR precursors, which enabled the efficient conversion of various unactivated alkenes into medicinally relevant alkylated N-heterocyclic amines. This approach offers an unexplored retrosynthetic disconnection for the synthesis of related molecules that commonly possess therapeutic value. Furthermore, this platform can be extended to the synthesis of densely functionalized heterocyclic amines by utilizing disulfides and diethyl bromomalonate as radical quenchers. Mechanistic investigations indicate an energy transfer (EnT) pathway involving the formation of a transient aromatic N-heterocyclic radical, radical addition to unactivated alkenes, and subsequent generation of the amination product through either hydrogen atom transfer (HAT) or radical addition processes.

Novel 5-aminopyrazoles endowed with anti-angiogenetic properties: Design, synthesis and biological evaluation. Eur J Med Chem 2023; 260:115727. [PMID: 37597434 DOI: 10.1016/j.ejmech.2023.115727] [Citation(s) in RCA: 1] [Impact Index Per Article: 0.5] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 05/19/2023] [Revised: 07/26/2023] [Accepted: 08/13/2023] [Indexed: 08/21/2023]
Abstract
The promising anti-angiogenetic properties of previously synthesized pyrazolyl ureas provided the rationale for the synthesis of novel 5-aminopyrazoles 2-5, differently decorated on the pyrazole nucleus. All the derivatives were tested by MTT assays and proved to be non-cytotoxic against eight different tumor cell lines and normal fibroblasts. An EdU proliferation assay was carried out on human foreskin fibroblasts and VEGF stimulated human umbilical vein endothelial cells which confirmed the absence of cytotoxicity of the compounds on human cells up to 20 μM concentration. To evaluate the influence of the newly synthesized pyrazoles on MAPK and PI3K signaling pathways, the phosphorylation of ERK1/2 and Akt was analyzed by Western blots from HFF and HUVEC cell lysates stimulated with growth factors in the presence or absence of the compounds. Pyrazoles 3b and 3c showed a significant inhibition of Akt phosphorylation in both tested cell lines with lower phosphorylation levels than the reference compound GeGe-3 in HUVEC. Furthermore, derivatives 2 and 3 appeared to strongly affect the migration of HFF cells in a wound healing assay, confirming their potential ability to interfere with the angiogenesis process. The new pyrazole library extends the structure-activity relationships of the previously isolated compounds and highlights the attractiveness of this chemical class for pathological cell migration and angiogenesis.

Abstract
Carbocations are important electrophilic intermediates in organic chemistry, but their formation typically requires harsh conditions such as extremely low pH, elevated temperature, strong oxidants and/or expensive noble-metal catalysts. Herein, we report the spontaneous generation of highly reactive carbocations in water microdroplets by simply spraying a diarylmethanol aqueous solution. The formation of transient carbocations as well as their ultrafast in-droplet transformations through carbocation-involved C-C and C-N bond formation reactions are directly characterized by mass spectrometry. The intriguing formation and stabilization of carbocations are attributed to the super acidity of the positively charged water microdroplets as well as the high electric fields at the water-air interfaces. Without the utilization of external acids as catalysts, we believe that these microdroplet reactions would pose a new and sustainable way for the construction of aryl-substituted compounds.

Abstract
Pyrazolines and pyrazolones are prevalent cores in drugs and bioactive molecules. Functionalizing them with heteroatoms on the ring improves or expands their clinical efficacy. However, a general method to selectively heterofunctionalize them at C4 and C5 is still elusive. Herein, we have demonstrated an iodine(III)-mediated construction of C4-heterofunctionalized pyrazolines from α,β-unsaturated hydrazones. The oxyacylated and aminated products, bearing a tertiary as well as a secondary stereocenter, were obtained via aza-Michael, followed by a C-O/C-N bond formation. A deprotection/oxidation sequence produced pyrazolones in a quantitative yield.

Abstract
Cancer remains a major health concern worldwide. The most frequently diagnosed types of cancer are caused by abnormal production or action of steroid hormones. In the present study, the synthesis and structural characterization of new heterocyclic androstane derivatives with D-homo lactone, 17α-(pyridine-2''-ylmethyl) or 17(E)-(pyridine-2''-ylmethylidene) moiety are presented. All compounds were evaluated for their anti-proliferative activity against HeLa cervical cancer cell line and non-cancerous kidney MDCK cells, where A-homo lactam compound 9A showed the greatest selectivity. Based on in vitro binding assays, N-formyl lactam compound 18 appeared to be the strong and isoform-selective ligand for ERα, while compound 9A displayed binding affinity for the GR-LBD, but also inhibited aldo-keto reductase 1C4 enzyme. Out of four selected compounds, methylpyrazolo derivative 13 showed potential for aromatase binding, while in silico studies provided insight into experimentally confirmed protein-ligand interactions.

Abstract
The aim of this review is to encapsulate the synthetic protocols and medicinal aspects of a wide range of heterocyclic compounds using the Vilsmeier-Haack (V. H.) reagent. These derivatives act as excellent precursors having different aryl ring functionalities and could be used for the synthesis of a variety of heterocyclic scaffolds. The V. H. reagent, a versatile reagent in organic chemistry, is used to formylate various heterocyclic compounds of medicinal interest. Due to the different chemical interactions, efficacy, and potency of V. H. reagents, plenty of heterocyclic compounds can be synthesized which serve as a constituent in various novel medications and acts as a bridge between biology and chemistry. These carboxylate moieties can effectively cooperate as precursors for several multi-component reactions (MCR) including Strecker synthesis, Bucherer-Berg reaction and post-MCR cyclization, modified variants with various pharmaceutical applications such as anti-tumor, anti-convulsant, anti-chitosomal and so on.

Abstract
Herein, we report an efficient method for synthesis of novel selenocyanates of amino pyrazole, amino uracil, and amino isoxazole derivatives using in situ triselenium dicyanide from the combination of malononitrile and selenium dioxide in DMSO medium. Using the same combination but changing the stoichiometry of reagents and sequence of addition and temperature, symmetrical selenoethers of amino pyrazoles and amino uracils were prepared in good yields. Furthermore, selenocyanates of amino pyrazoles were utilized for the synthesis of corresponding alkynyl selenides in the presence of CuI and Cs2CO3. The salient features of this methodology are inexpensive starting materials, short reaction time, and good to very good yields. This method is also applicable for the gram-scale synthesis of selenocyanates of amino pyrazoles and amino uracils.

Abstract
Catalpol, a natural product mainly existed in plenty of Chinese traditional medicines, is an iridoid compound with the comprehensive effects on neuroprotective, anti-inflammatory, choleretic, hypoglycemic and anticancer. However, there are some disadvantages for catalpol such as a short half-life in vivo, low druggability, stingy binding efficiency to target proteins and so on. It is necessary to make structural modification and optimization which enhance its performance on disease treatments and clinic applications. Pyrazole compounds have been reported to have excellent anticancer activities. Based on the previous research foundation of our research group on iridoids and the anticancer activities of catalpol and pyrazole, a series of pyrazole modified catalpol compounds were synthesized by principle of drug combination for serving as potential cancer inhibitors. These derivatives are characterized by 1H NMR, 13C NMR and HRMS. The efficacy of anti-esophageal cancer and anti-pancreatic cancer activities were evaluated by the MTT assay on two esophageal cancer cells Eca-109 and EC-9706, and two pancreatic cancer cells PANC-1, BxPC-3 and normal pancreatic cell line HPDE6-C7, which showed that the compound 3e had strong inhibitory activity against esophageal cancer cells, this providing a theoretical basis for the discovery of catalpol-containing drugs.

Abstract
A pyrazole nucleus is an easy-to-prepare scaffold with large therapeutic potential. Consequently, the search for new pyrazole-based compounds is of great interest to the academic community as well as industry. In the last ten years, a large number of papers and reviews on the design, synthesis, and biological evaluation of different classes of pyrazoles and many pyrazole-containing compounds have been published. However, an overview of pyrazole derivatives bearing a free amino group at the 3, 4, or 5 position (namely, 3-aminopyrazoles, 4-aminopyrazoles, and 5-aminopyrazoles, respectively) and their biological properties is still missing, despite the fact that aminopyrazoles are advantageous frameworks able to provide useful ligands for receptors or enzymes, such as p38MAPK, and different kinases, COX and others, as well as targets important for bacterial and virus infections. With the aim to fill this gap, the present review focuses on aminopyrazole-based compounds studied as active agents in different therapeutic areas, with particular attention on the design and structure-activity relationships defined by each class of compounds. In particular, the most relevant results have been obtained for anticancer/anti-inflammatory compounds, as the recent approval of Pirtobrutinib demonstrates. The data reported here are collected from different databases (Scifinder, Web of Science, Scopus, Google Scholar, and Pubmed) using "aminopyrazole" as the keyword.
